My pick is C
because....if the base for two "same area" traingles is same and the other two sides of one the traingles are equal....then oviously the other two sides of the other traingle should also be equal.....for the height of the traingles to be same...

I would go with E.
(1) if a quadrilateral is devided into two triangles of equal area, its not necessarily a parallelogram. The figure could be a kite as well. INSUFFICIENT
(2) if two adjecent sides are equal, we don't know anything about the two other sides, i.e. we don't know whether they are parallel or not. The figure could be a trapezoid, or just a general quadrilateral. INSUFFICIENT
